'10 all whom it may concern.-

Be it knownthat I, PHILLIP SOHMITT, a citizen of the United States,residing at Parker,

in the county of Turner and State of South De kota, have invented newand useful Improvesame is to construct a clamp for securing thetop of ahay-rack on the lower portion without using bolts, which clamp will beeasily detachable and will permit the top to be removed without the useof a wrench.

The simple and novel construction employed by me in carrying out myinvention is fully described and claimed in this specification andillustrated in the accompanying drawings, forming .a part thereof, inwhich- Figural is a perspective of my device ready for locking. Fig. 2is a like view of the same locked. form of my device unlocked. Fig. 4 isasimilar view of the same locked.

Like numerals of reference designate like parts in the different viewsof the drawings.

The numeral 1 designates a bed-piece of my rack, and 2 a crossbarresting on said bedpiece. A side bar 3, forming a part of the detachableportion of my rack, rests on the cross-bar. A standard 4: is footed onthe bedpiece 1 and is rigidly secured by nuts 4 The" A hooked "catch 9is formed on the free end of the lever 6 to serve to engage the standard4 to limit the swing of the lever 6 and to secure it in its lockedposition.

In operationth'e lever 6 is raised up into the position shown in Fig. 1,with the hook 7 above the side bar 3. The lever 6 is then depressed,thereby bringing the hook 7 into engagement with the side bar 3 and thecatch 9 into engagementwith the standard 4:. The catch 9 is made longenough so that the ic ver passes the dead-center on its downwardmovement and is therefore securely locked.

. the arm 12.

Fig. 3 is a perspective of a modified- The manner of disengaging thehook 7 to remove the rack is obvious.

In the modified form illustrated in Figs. 3 and 4. a standard 10 isemployed, which has a hooked arm 11 thereon, which engages the cross-bar2. An. arm 12 is aiso formed on the standard 10 to serve as a fuicrumfor a lever 13, having prongs M thereon which engage A book 15, similartothe hook 7. is carried by the lever and engages the side bar 3. Thelever 13 is provided with a catch 13", similar to the catch 9 and for anidentical purpose. The operation of the modifiediorm Wiil be obviousfrom what has already been saic y I do not wish to be limited as. todetails of construction, as these may be modified in many particularsWithout departing from the spirit of my'invention.

Havingthus described my invention, what I claim as new, and desire tosecure by Letters Patent. is
